Order: Passeriformes. Family: Callaeidae. New Zealand status: Endemic. Conservation status: Extinct. Artists' impression of a female huia. The iconic huia was the largest of the five New Zealand wattlebird species. It was a striking large songbird, mainly black with long white-tipped tail feathers.

Female and male huia had dramatically different bill sizes and shapes; this was the most extreme sexual bill dimorphism of any bird species. A fleshy orange wattle hung at the base of each side of the bill, and was often held pressed under the chin. Maori named the bird after its loud distress call, described as "a smooth, unslurred whistle rendered as uia, uia, uia or where are you?

New Zealand wattlebirds are crow- or starling-like songbirds. Genetic comparisons suggests that they shared a common ancestor with the satinbirds, berrypeckers and longbills of New Guinea. Together they form the New Zealand endemic bird family Callaeidae, comprising North and South Island species of kokako and saddleback tieke , and the now extinct huia. All have or had rounded wings, limited powers of sustained flight, and use bounds, hops and jumps to move around forests.

The huia was a magpie-sized glossy black bird. In fresh plumage, the black feathers had a green and bluish-purple metallic sheen. The long black tail feathers had cm white-tips, forming a bold white band across the tail-tip. The bill was pale ivory grading to bluish-grey at the base, and yellow at the gape. The female's long, slender, decurved bill was mm long; the male's heavier, less-curved bill was mm long.

A bright orange or yellowish oval fleshy wattle up to 24 mm by 16 mm was attached at the base of each side of the bill, and was often held curled under the bill. The long legs were bluish-grey. Juveniles were brownish-black with an off-white tail band, becoming whiter with age, and white fleshy wattles becoming orange with age.

Similar species: both saddleback species resemble dwarf versions of the male huia, but with red wattles and rufous brown "saddle" markings on the back. Pre-human huia bone remains indicate it was common throughout the North Island, but absent from the South Island. Huia were widespread but sparse after European settlement, in the eastern North Island from Huiarau south, with most records from the Ruahine, Tararua and Rimutaka ranges and northern Wairarapa, also the hills around Wellington.

Genetic study indicates huia had "moderate to high" historical population of 34, to 89, birds; probably higher pre-human settlement. Predation by introduced mammals and, to a lesser extent, human hunting, was the likely cause of huia extinction.

Maori traditionally prized and wore huia tail feathers as a mark of status. Tail feathers became fashionable in Britain after the Duke of York was photographed wearing one during a visit to New Zealand.

Overseas bird collectors and museums bought mounted specimens and tail feathers. Austrian naturalist Andreas Reischek took pairs between and New Zealand naturalist Walter Buller recorded that 11 Maori hunters took huia skins from forest between Manawatu Gorge and Akitio during one month in Thousands of huia were exported overseas.

Protection measures enacted in the s were poorly enforced. Two male birds kept at London Zoo in the s died in captivity. Plans to transfer huia to Kapiti and Little Barrier island reserves never eventuated. A captive pair kept by Buller hopped from branch to branch, fanning their tails, and caressing bills while making low twittering contact calls.

This was thought to be a courtship display. Male huia fed females during courtship, incubation and brooding, as do kokako and saddleback. Huia bred as monogamous pairs during September-February. The large saucer-like nest with cup-shaped centre had thick walls of woven grass, leaves and stems.

The stone-grey eggs with purplish-brown markings were laid in September-October. Incubation was mainly by the female. One brood of nestlings was reared, mainly in November. Young remained in the family group, fed by both adults, for at least three months.

There is also an unconfirmed record of a nest " in a rotten maitai tree, about fifteen feet from the ground" containing four eggs " laid in the rotten dust ". Male huia used their bills as a "pick-axe" to dig into decaying wood, exposing and extracting huhu larvae and other insects. Females probed deeper using their longer, more decurved bill to extract larvae from more solid wood. Buller observed male-to-female transfer of food, but never in the other direction; he also described a pair apparently co-operating to hunt weta.

Riley quoted Caldwell: "He hops along with a fine spider and very politely offers it to his better half, who seems to always appreciate his fine attention. And so they keep close together Oliver quoted Wright: "I have watched them in pairs hunting for wetas. The male would tear away the outer part of a green sapling. The female then tried to retrieve the weta with her long slender bill. If not successful she would stand back while the male tried to enlarge the hole. Unless the tree was a maire the birds would generally succeed, and would then fly away with the weta".

Different bills may have allowed pairs to exploit a wide range of food sources in different microhabitats, increasing the amount of food they extracted from a territory. Huia were "ecologically naive", with little fear of humans. They seldom flew above tree-height, moving through the forest by hopping or bounding along branches and on the ground, similar to kokako, and were reputedly able to jump "twenty feet" at a time. Potts described huia, " bounding with a slight opening motion of the wings, flying only very short distances ".

They were reportedly the first bird to call in the "early dawn". The calls of the sexes differed. Duetting pairs repeatedly called alternately, answering one another; they called with their bill pointed degrees from vertical.

Huia mainly consumed wood-dwelling insects and their larvae, including huhu, weta, mantis, butterfly, also spiders, taken from decaying wood, bark, lichen, moss, ferns and the ground. They also ate native forest fruits, including hinau, pigeonwood, Coprosma , and kahikatea, and " vegetable matter ".

In the s several unrecorded sightings of the Carolina Parakeet were reported in places like Alabama, Florida, and South Carolina. In the 19th century, the valley, mainly marshy ground and a shallow lake, was inhabited by Ghawaraneh Bedouin [6] who wove matting from the papyrus with which they built their homes. Often they exploited the strong pair bond by capturing one of a pair, which would then call out, attracting its mate, which could be easily captured. Even the early Europeans who came to America hunted the Auks for food and used them as bait in fishing. A common kingfisher hunts from a strategic vantage point in the reeds of Hula Lake. The last Giant Moa sighting was well over years ago. New Zealand status: Endemic Conservation status: Extinct.

Beautiful species that call the Hula Valley home | From the Grapevine

The location of the Hula Valley, in the heart of the Great Rift Valley, and its diverse and rich habitats, creates one of the top birding sites in the world. During autumn and spring the Hula Reserve, Agamon and surrounding fields, transform into a bustling fueling and resting point for millions of migratory birds from hundreds of different species.

Thousand of Eurasian Cranes crowd the winter skies with their characteristic "grus. The Hula Valley is also a paradise for its nesting bird species, some under global threat of extinction — such as the Basra Reed Warbler, Marbled Duck and the reintroduced, awe inspiring, White-Tailed Eagle.

Also, the rarest amphibian in the world — the Hula Painted Frog, the living fossil causing turmoil in the scientific communities in recent years - has been re-discovered here after thought to be extinct from the world for half a century! This is our wonderful reality at the Hula Valley Birding Center. The Hula Valley Birding Center aspires to be a hub of scientific activities in a scale not seen in Israel before.

We are working to conserve and preserve all these natural treasures through education, tourism, and working with the local community, promoting the protection of birds and their habitat in this beautiful and valuable area. The main goal of the center is to preserve the diversity of birds and their habitats. Nature conservation and monitoring are in essence the "bread and butter" of the HVBC.

Regular daily activities include monitoring the different populations, recognizing changes and trends in the field and acting to protect the species' diversity and habitats. The ringing station staff offers professional guiding about birding and nature conservation to the various groups arriving at the Agamon.

Tens of thousands of school children, university students and the general public have visited the ringing station in past years. In recent years the HVBC has been conducting several surveys whose goal was to determine the impact of constructing a "wind farm" with turbines to produce electricity on migratory and resident bird species. The accumulated data was used to set the standards by which to construct the farms while causing minimal impact on the natural environment. An encompassing survey aimed at mapping the breeding birds' population of the Hermon Mountain.

The highest mountain in Israel is home to no less than 17 breeding bird species that cannot be found any where else in the country.

The unique and fragile habitats of the Hermon are under many threats. The survey provides valuable information about the size of the populations, their composition and level of vulnerability and recommends desired measures to be taken in order to protect the unique species of the mountain top.

In the Hula Valley and its surroundings there are several nesting species under global threat of extinction — lesser kestrel, marbled duck and Ferruginous Duck. The Hula Valley is an important wintering ground for many birds of prey, some of which under global threat of extinction, such as the Great Spotted Eagle, Imperial Eagle and Pallid Harrier.

The center conducts surveys in order to monitor the different species, so they can be better protected. The Pratincole Initiative came to life after emergency measures had to be taken in order to save one of the last nesting colonies of Collared Pratincoles in Israel. Even today the state of the Pratincoles in Israel is critical with less than breeding pairs.

But there is reason for hope due to the rise in awareness among the general public and in particular among the farmers in whose fields the Pratincoles nest. Joint teams of farmers and nature lovers not to imply one is not the other act in the Hula Valley and Beit Shean Valley in order to prevent further destruction of the nesting colonies. In the HVBC education receives very high priority.

Introducing the public to the acquired knowledge and creating familiarity with the fascinating world of birds, are the correct and effective ways to protect bird species and nature in general, in both present and future times. The ringing station in the Agamon-KKI serves as an aperture to the center's activities. Each year thousand of visitors discover the wonderful world of birds with the help of the SPNI researchers working in the station.

This is a golden opportunity to close encounter birds and understand the importance of protecting them in addition to simply enjoying the outdoors in the heart of the Agamon.

Once a month, a "communal observation survey" takes place. It is a joint activity for birding and nature enthusiasts from the greater region. The communal observation takes place in a different site each time, guided by the HVBC professional staff and is free of charge. The HVBC conducts birding activities in the site to help raise awareness to the marvelous natural world of the park.

Nature and agriculture can exist side by side! In a new initiative of the birding center, Hula Valley farmers and Agamon-KKL, we promote cooperation between nature loving farmers and non-farming nature lovers — for the protection of natural merits in the agricultural fields. The initiative includes monthly leaflets for the farmers in topics of nature and ecology, a joint panel for discussing nature conservation issues and more. Birding tourism has been growing at a terrific rate all over the world, and in Israel in particular.

Millions of tourists "migrate" every year following the birds' global passage, which inevitably leads many to Israel. HVBC is partner in the promotion of both national and international birding tourism. The HVBC conducts guided birding tours for groups and individuals of all ages all year long. You are invited to come and enjoy the wealth and beauty of birds through guided tours with some of the best birdwatchers in the country.

Each year thousands of visitors come to see birds in the north of the country and thus "put birding on the Israeli map". HulaValleyBird Festival has been taking place each winter since , and is gaining further momentum every year. Birders from all over the world as well as Israel, come to experience rare birding treats in the Hula Valley, such as the wintering cranes and raptors roosting colonies — giving the festival and the Hula Valley global publicity.
